ASSIGNR TO IBRGGIE WNDOW CORPORA- TON, OF CHICAGO, ILLINGIS, A CORPORTTGN 0F TLLNOIS WINDOW CONSTRUCTIGN Application filed April 2Q,

rihis invention belongs to the general type of windows wherein one sash slidably moves in contact with or in proximity to a cooperat ing sash. It 1s a companion case with one heretofore led by me pertinent to improvetion of a window of well known type in which I of the usual type.

the sashes 1 1 move one npon the other;

Fig. 2 is a transverse section on the line 2 2 of Fig. 1;

Fig. 3 is a central vertical section on the line 3 3 of Fig. 1;

Fig. 4 is a section line 4 4 of Fig. 3, showing the weight connections, a fraction of the sash and a form of spring which may be employed in the device; and

Fig. 5 is a section on the line 5 5 of Fig. 1 showing a section through the lower part of the sash and sill.

Referring to Fig. 1, the sashes 1 1 are contained in a frame provided with jambs As shown, the sash on each side preferably extends the vertical side of the sash, and as at 2 2 is constructed with a box-like end 3 which, as shown,-is provided with a telescoping part 4 adapted to slide in the box 3. Suitable springs 5 extending between the outer end of the telescoping part 4 and the base 6 of the box normally hold the telescoping member to its outer limit of movement. 7 indicates the "i jamb of the window frame against which the telescoping part 4 is forced by the spring, insuring a snug and close fit between the two parts excluding air and dust.

In the preferred form, the jamb and its telescoping part 4 have their meeting faces formed to cooperate as stated. As shown, the amb 7 is beveled while the faces of the telescoping part 4 is provided with a reverse bevel so that the two fit together snugly. Any preferred form of contour may be adopted, however.

Referring to Fig. 4, 8 indicates the weightpulley attached to a clip 9 which is secured to the top of the sash. 5 is a spring vertically arranged within the box 3 tending to hold 1929. elial N0. 353,107.

the telescoping parts 4 to their outer limit of movement, as state-d. Any preferred type of spring or resilient means may be employed.

Carrying out the idea for excluding wind and dust, Fig. 3 shows the top part or rail of a window preferably equipped with a box 11 having its top edge formed to cooperate with the top jamb 12. The bottom rail 13 may be similarly constructed, cooperating with the window sill 14.

As shown the improvement is particularly adapted for use with metal windows. It is obvious, however, that it is equally adapted for use with wooden sash, those skilled in the art readily making such slight modifications as may be required.

Having thus described my invention, it is obvious that various immaterial modications may be made in the same without departingfrom the spirit of my invention; hence, l do not wish to be understood as limiting` myself to the exact form, construction, arrangement, and combination of parts herein shown and described or uses mentioned.

l/Vhat l claim as new and desire to secure by Letters Patent is:

l. A window structure comprising sliding sash members provided with a recess formed in the longitudinal edges thereof, in combination with laterally movable members slidably mounted in and closely fitting said recesses, a plurality of relatively flat V-shaped strips of material each having its apex fastened to the sash member and its ends fastened to said slidable member to provide resilient means arranged to force said slidable members toward their outer limit of movement with the adjacent faces of the slidable member and the window amb in cooperating relation, one of said faces having a convex bevel and the other a concave bevel.

2. A. window structure comprising sliding sash members provided with a recess formed in the longitudinal edges thereof,'in combination with laterally movable members slidably mounted in and closely fitting said recesses, a plurality of relatively fiat V-shaped strips of material each having its apex fas tened to the sash member and its ends fastened to said slidable member to provide resilient means arranged to force said slidable members toward ltheir outer limit of movement with the adjacent faces of the slidable member and the Window jamb in cooperating relation, the cooperating faces of said members being convexly beveled and of the j amb being ooncavely beveled.

In witness whereof I hereunto subscribe my name this 26th day of April, A. D., 1929.

RICHARD S. BROGIE."
